How Old Are You When This Happened?

I would drive by his house because my grandma lived in beverley hills, and she one day told me that's where steve martin lives. And so i said, wil you sign it in the street? And which i thought was a pretty good joke at the time. How old were you when this happened? I think i was 12 or 13. Nso rite right at the age where it's not like a little kid doing what he did.
